Abstract: This paper presents the design of the user interface for a robotic spraypyrolysis system used in deposition on planar surfaces. The study takes into consideration theoptimization of the control characteristic parameters at the spraying process. CAD software environment is used to design thevirtual model at the robotic system, while RobotStudio is used to develop theuser interface. The design variables for optimization refer tothe spray pyrolysis deposition parameters (the number of passes, the pressureof the carrier gas, the orientation and the velocity of spray nozzle, thetemperature of the substrate). The main purpose of the paper is to obtain materials with controlled properties byspray pyrolysis, using a simple algorithm. The surfaces resulted by spraypyrolysis were analyzed using theAFM (Atomic Force Microscopy) technique.

Abstract: In this paper a human upper limb robotic system is analyzed through an experimental study. The experimental analysis aim is to validate this robotic system type in order to use it in some kinetotherapy programs for the human upper limb recovery. The robotic system experimental research was performed by using special equipment called CONTEMPLAS which enables to evaluate angular variations in 3D environment. The equipment used in this research has two high-speed cameras which can record and establish the angular variations developed at the robotic system joints level. This paper consists of three main parts. In the first part there is an actual study of the robotic systems specially designed for the human upper limb rehabilitation, where the robotic system proposed for this experimental research is described. The second part includes some literature aspects regarding the movements developed by the human upper limb, and in the third part the experimental research is described in detail.

Abstract: Article deals with robotic production systems in automotive industry, focusing on the procedures of projecting. Based on the methods of modularity we can create process of the project design automation systems, allowing us to minimize costs associated with formation of different modifications of solutions workplace. The possibility of using Computer Aided (CA) methods that allow to simplify and speed up the project and construction works

Abstract: The paper deals with the kinematics structures of the peripheral devices used in robotic welding systems. There are two categories of such devices: either manipulators for extending the working range of the existing robots or positioners for supporting the parts to be processed. In certain cases, the last ones are also turning the welding parts, contributing to the technological movement. Starting from the kinematics structures a series of these devices, some theoretical models as well as practically built machines on their basis are shown.

Abstract: A stereo visual servo robotic system is developed on Nios II SOPC developing board with ALTERA FPGA chip to manipulate a retrofitted Mitsubishi RV-M2 robotic system. The 3-D position information between the target and stereo vision system can be extracted by low cost CMOS stereo vision algorithm first. Then, the relative motion between the robotic end-effector and the target can be planned to guide robot arm to catch the object. The fuzzy sliding mode control algorithm is employed to monitor the trajectory motion of each joint. The experimental results show that this visual servo robotic system can track and catch a moving target in 3D space and execute some interaction functions with player.

Abstract: In this paper, we proposed two wheeled-type in-pipe modular robotic systems. These modular systems are composed of driving modules (which use mechanisms with articulated elements) and passive modules. The first module (driving module) generates the traction force. The passive module is necessary to carry the control electronic equipment and for the transport of the needed equipment for realization of the in-pipe inspection. The joint disposed (universal join) by the two modules of the robot offers the capacity of orientation of this one.

Abstract: This paper presents fabrication and characterization of a pressure-sensitive polymeric composite on a flexible readout circuit as an artificial skin. Porous nylon was used as the matrix, which provided skin-like mechanical properties. Inside the matrix, polypyrrole was electrochemically deposited and acted as conductive dopant. The fabrication was detailed. The conductivity of the fabricated composite increased when a compressive load was applied. The electro-mechanical characteristics of the composite were measured.
